HANGER.

SPECIFICATION forming part of Letters Patent No. 752,501, dated February16, 1904.

Application filed August 8, 1903.

To all whom, t may concer-71,:

Beit known that I, MONTRAVILLE MWVOOD, a citizen of the United States,residing at Schenectady, county of Schenectady, State of New York, haveinvented certain new and useful Improvements in Trolley Hangers, ofwhich the following is a specification.

The present invention relates to means for suspending and insulatingelectric conductors, and more particularly to hangers for trolley-Wires.

The object of my invention is to provide a highly-efficient device ofthis character consisting of few parts, which may be readily taken apartby hand to permit a broken insulator to be replaced or for any otherreason, reconnected, and securely locked against any tendency to workloose under the incessant shocks and vibrations to which devices of thisclass are subjected.

A further object of my invention is to provide an arrangement of theparts of a hanger so that the joints between them will be efficientlyhoused, to thereby prevent their becoming frozen or rusted together.

The invention comprises a suspender provided with an inverted-cup-shaped recess adapted to receive the head of an ordinary insulatedstud, a nut or screw-threaded ring surrounding the insulated stud andhaving a drip-flange at its lower end and a threaded upper end providedwith a shoulder adapted to be screwed into the cup-shaped recess againstthe shoulder on the lower surface of the head of the stud and alockingbolt longitudinally movable in an upwardly-extending recess inthe suspender and adapted to engage at its outer end with notches formedin the periphery of the drip-flange and prevent the nut orscrew-threaded ring from turning.

The invention will be readily understood by reference to the followingdescription and the accompanying drawings, forming a part of thisspecification, in whichg Figure 1 is a part side elevation and partsection of trolley-hanger embodying one form of my invention and towhich is connected a serial No. 168,738. (No model.)

standard ear by means of an ordinary insulated stud, and Fig. 2 is aright-hand elevation of the same.

The suspender A shown in the drawings consists of a cylindrical bodypart 1 and a single downwardly-curved arm 2, in the end of which is aneyc 3, through which the guywire may be attached in the usual manner.rl`he body part 1 hasformed in its lower surface an inverted-cup-shapedrecess 4 of a size to readily receive the flat cylindrical head of aninsulated stud B and having a plane end protected byy a disk 5, ofelastic material, against which the head of the stud normally presses,and a cylindrical side wall provided near its lower end with avscrew-thread by which the nut or screw-threaded ring 6 is held inposition. The nut or screw-threaded ring 6 has a shoulder 7 formed atits upper end to engage the lower surface of the head of the insulatedstud B and a central aperture 8 of a slightly-greater diameter than theshank of the stud, so that the latter may pass readily therethrough. Adownwardly -projecting flange or petticoat 9 is formed upon the lowerend of the nut or ring 6 and strengthened by radial webs 10, and in theouter edge of the iange or petticoat 9 are cut a series of verticalslots 11, which cooperate with a lockingbolt l2 to hold the nut orthreaded ring from turning and also serve to roughen the edge thereof,so that the hand may obtain a firm hold when disconnecting or assemblingthe parts.

The locking-bolt 12 is carried in an upwardlyeXtending recess 13, formedin the arm of the suspender, and a lug 14, projecting from the-loweredge thereof into proximity to the petticoat or flange 9, and consistsof a short metal bar provided with a tapered outer end 15 and a shoulder16 at its lower edge adapted to engage a corresponding shoulder 17formed in the recess 13 when raised out of engagement with the slots 11.

When it is desired to remove the insulated stud B for any cause, the nutor threaded ring 6 is first unlocked by raising' the bolt 12 intoinoperative position, either by the lingers or by passing a small tool,such as a screwdriver, between its beveled outer end and the flange orpetticoat 9. The latter is then seized by the hand and unscrewed fromthe suspender A. The stud B may now be unscrewed from the ear C by awrench in the usual manner and withdrawn from the nut or threaded ring6. In replacing the stud B these operations are reversed and thethreaded ring 0r nut screwed upon the head of the stud with as greatforce as desired and locked by slightly raising the outer end of thebolt l2 and permitting it to descend into one of the slots l1 in theedge of the flange or petticoat.

It is to be noted that according to my construction there are nocrevices or joints in which water may lodge to freeze or rust orotherwise interfere with the free operation of the parts and that theparts are so arranged and constructed that they cannot become injured ordisplaced by impact with the trolley head or pole.

I do not desire to restrict myself to the particular' construction orform of parts shown and described herein, for it is apparent that theymay be changed and modified without departing from my invention.

IV hat I claim as new, and desire to secure by Letters Patent of theUnited States. is

l. A hanger for electric conductors comprising a suspender provided withan inverted-cu pshaped recess adapted to receive the head of aninsulated stud, a nut or threaded ring adapted to be screwed into thelower end of said recess, and means for locking said nut or ring inposition.

2. A hanger for electric conductors comprising a suspenderprovided withan inverted-cupshaped recess adapted to receive the head of an insulatedstud, a nut or threaded ring adapted to be screwed into the lower end ofsaid recess and provided with a drip-flange or petticoat, and meansadapted to engage said ilange or petticoat and lock said nut inposition.

3. A hanger for electric conductors comprisinga suspender provided witha recess adapted to receive the head of an insulated stud, a nut orthreaded ring through which the said stud may pass and adapted to bescrewed into said recess, and a longitudinally-movable bolt carried bysaid suspender and adapted to engage said nut or threaded ring to lockit in position.

4C. A hanger for electric conductors comprising a suspender providedwith a recess adapted to receive the head of an insulated stud and abolt-recess, a nut or threaded ring adapted to be screwed into thefirst-mentioned recess, and a bolt located in the second recess and adaptcd to engage and lock said nut or ring in position.

5. A hanger for electric conductors comprising a suspender provided withan inverted-cupshaped recess and an inwardly-projecting recessed lug, anut or threaded ring adapted to be screwed into said cup-shaped recess,and a bolt located in said recessed lug and adapted to engage and locksaid nut or threaded ring in position.

6. A hanger for electric conductors comp rising a suspender providedwith an inverted-cupshaped recess and an inwardly-projecting rccessedlug, a nut or threaded ring adapted to be screwed into the cup-shapedrecess to sustain an insulated stud therein and provided with adrip-Harige having a series of slots in its outer edge, and a boltlocated in said recessed lug and adapted to engage the slots in saiddrip-flange.

In witness whereof I have hereunto set my hand this 6th day of August,1903.
